Title: Guide rail for a knee joint orthosis
Inventor: GRUNDEI HANS
IPC: A61F5/01
Filed: 1988-07-29
Abstract: There is described a guide rail with a joint for a knee joint orthosis which comprises a first articulated member to be fastened on the thigh and a second articulated member to be fastened on the calf, the two parts being connected to each other via the joint so as to be pivotable between an extended position and a flexed position. The first articulated member is supported by a runner from above on a sliding track of the second articulated member. In the extended position the runner is secured against lifting off the sliding track by a guide element fastened on the second articulated member, specifically in a manner such that the runner is braced in this position between the sliding track and the guide element over the entire bearing surface. Bracing is cancelled on pivoting the articulated members into the flexed position. With increasing pivoting angle, the first articulated member can be increasingly moved in the dorsal and ventral directions, with reduction of the bearing surface of the runner on the sliding track, relative to the second articulated member. A spring force acting upon the first articulated member supports pivoting of the articulated members into the extended position.

Title: Method and device for measuring the leakage of a device operated with a gaseous medium
Inventor: VORBERG KARLHEINZ DIPL ING
IPC: G01F1/52
Filed: 1988-11-23
Abstract: The invention relates to a method and a device for measuring the leakage of a device operated with a gaseous medium. The leakage flow from the device is introduced from above into a measuring tube which is immersed in a liquid. The measuring tube is divided into several measuring sections, whose cross-sections increase in the flow direction of the leakage flow. Each measuring section is equipped with two sensors which detect the beginning of the measurement and the end of the measurement and give corresponding signals to a computer which determines the leakage flow from these signals and from the volume of liquid expelled by the leakage flow in the measuring tube. The leakage measuring device has a very high measuring range width of, for example, 1 : 10,000, and it can work fully automatically. The device manages completely without mechanically moving individual parts and is therefore simply constructed, rugged, safe against overload and insensitive to dirt.

Patent DE-3918765-A1 (DE)
Inventor: GATZ CARSTEN
IPC: B41M3/14
Filed: 1989-06-08
Abstract: A security paper can be used to produce documents which can be identified as genuine by means of a colour reaction system consisting of a colour-forming component and a colour-developing component and based on the principle of pressure-sensitive duplicating paper. The colour-forming component is applied to the paper, which contains the colour-developing component, by means of a marking device. A number of drawbacks are associated with known security systems for documents based on the principle of pressure-sensitive duplicating paper. The aim of the invention is to overcome these drawbacks. To this end, the security paper is placed in contact with a marking liquid which contains a colour-forming component. The reaction between the colour-developing component present in the paper and the colour-forming component occurs in the paper itself instead of on the surface as in conventional papers. The marking penetrates the paper and may even strike through on the other side, where it forms a mirror image. This marking cannot be removed from the document without destroying the document itself. A further major advantage of the invention is that a paper with an incorporated colour-developing component is a true security paper, i.e., comparable with conventional special papers (with fluorescent inlays, small engravings, watermarks, metal threads, etc.) which are note available to the general public. This appreciably enhances the security.
